Kaho thibela likokoana-hloko, ntlafatsa bophelo bo botle ba 'mele, ho laola boleng ba metsi, leho matlafatsa sesole sa mmele, e khothalletsa nts'etsopele ea tlhapi e tala le e phetseng hantle ea metsing.

Potassium diformate, joalo ka mofuta o mocha oa motsoako oa letsoai oa organic acid, o bontšitse tebello e pharaletseng ea ts'ebeliso indastering ea temo ea metsing lilemong tsa morao tjena, haholo temong ea shrimp moo e bonts'ang litlamorao tse ngata. Motsoako ona, o entsoeng ka formic acid le ion potassium, o hlaha e le mokhoa o mong o loketseng oa lithibela-mafu ka lebaka la mokhoa o ikhethileng oa antibacterial le mesebetsi ea taolo ea 'mele.

Mesebetsi ena e kopana ho theha motheo oa bohlokoa oa tekheniki bakeng sa bophelo bo botle ba metsing.

Mabapi le phetoho ea lithibela-mafu, mochine oa antibacterial oa potassium diformate o na le melemo e mengata. Ha potassium diformate e kena ka har'a shrimp, e ikarola ebe e ntša limolek'hule tsa formic acid tikolohong e nang le asiti. Limolek'hule tsena tsa asiti ea formic li ka kenella ka har'a lisele tsa baktheria 'me tsa ikarola ho li-ion tsa haedrojene' me tsa etsa li-ion sebakeng sa alkaline cytoplasmic, ho baka phokotseho ea boleng ba pH ka har'a lisele tsa baktheria le ho kena-kenana le mesebetsi ea bona e tloaelehileng ea metabolism.

Lipatlisiso li bonts'itse hore potassium diformate e na le phello e kholo ea thibelo ho libaktheria tse tloaelehileng tsa shrimp pathogenic tse kang Vibrio parahaemolyticus, Vibrio harveyi, le Escherichia coli, e nang le bonyane ba inhibitory concentration (MIC) ea 0.5% -1.5%. Ha ho bapisoa le lithibela-mafu, mokhoa ona oa 'mele oa ho thibela likokoana-hloko ha o khothalletse ho hanyetsa baktheria 'me ha ho na kotsi ea masala a lithethefatsi.

Taolo ea bophelo bo botle ba mala ke mosebetsi o mong oa mantlha oa potassium diformate. Ho lokolloa ha formic acid ha ho thibele libaktheria tse kotsi feela, empa hape ho etsa hore ho be le microenvironment e ntle bakeng sa ho ata ha li-probiotics tse kang libaktheria tsa lactic acid le bifidobacteria. Ntlafatso ea sebopeho sena sa tikoloho ea likokoana-hloko e ntlafatsa haholo ts'ebetso ea mala le ho monya hantle ha mala.

Potassium diformatee bonts'a litlamorao tse ikhethang tse sa tobang taolong ea boleng ba metsi. Sebakeng sa setso sa metsing, hoo e ka bang 20% ​​-30% ea phepelo ea naetrojene ha e monyele ka botlalo 'me e tšeloa ka metsing, e ba mohloli o ka sehloohong oa ammonia nitrogen le nitrite. Ka ho ntlafatsa ts'ebeliso ea phepo e nepahetseng, potassium diformate e fokotsa ho ntšoa ha naetrojene ka katleho.

Lintlha tsa liteko li bontša hore ho eketsa 0.5%potassium diformatee ka fokotsa maemo a naetrojene mantleng a shrimp ka 18% -22% le phosphorus ka 15% -20%. Phello ena ea phokotso ea mosi e bohlokoa ka ho khetheha lits'ebetsong tsa metsi aquaculture aquaculture (RAS), e ka laolang bongata ba nitrite metsing a ka tlase ho 0.1mg/L, hole ka tlase ho moeli oa polokeho bakeng sa shrimp (0.5mg/L). Ho feta moo, potassium diformate ka boeona butle-butle degrades ka carbon dioxide e le metsi ka metsing, ntle le ho baka tšilafalo ea bobeli, e etsa hore e be tlatsetso ea botsoalle tikolohong.

Phello e matlafatsang 'mele ea ho itšireletsa mafung ke pontšo e' ngoe ea boleng ba tšebeliso ea potassium diformate. Mala a phetseng hantle ha se feela setho sa ho monya limatlafatsi, empa hape ke tšitiso ea bohlokoa ea 'mele ea ho itšireletsa mafung. Potassium diformate e fokotsa karabelo ea ts'ebetso ea ho ruruha ka ho laola tekano ea gut microbiota le ho fokotsa ts'usumetso ea libaktheria tsa pathogenic ho epithelium ea mala. Lipatlisiso li fumane hore ho eketsa potassium diformate ho li-shrimp ho eketsa palo ea li-lymphocyte tsa mali ka 30% -40%, 'me ho matlafatsa haholo ts'ebetso ea li-enzyme tse amanang le 'mele tse kang phenoloxidase (PO) le superoxide dismutase (SOD).

Lits'ebetsong tse sebetsang, tšebeliso ea potassium diformate e hloka karo-karolelano ea mahlale. Chelete e khothaletsoang ea tlatsetso ke 0.4% -1.2% ea boima ba phepo, ho ipapisitse le sethala sa ho ikatisa le maemo a boleng ba metsi.
